To all whom it may concern:

. Be it known that l[, ARTHUR a citizen of the United States, andresident of Chicago, county. of Cook, and State of ll1ino1s,.haveinvented certain new and useful Improvements in Gar-Roofs, of which thefollowing isaspecification, and which object being to provide improvedmeans for attachlng the plates to the car so as to secure flexibility,permitting the weaving or twisting action of the roof which occurslnservice, without throwing. strain upon the I plates.

7 The invention consists in" a structure such as ishereinafterdescribed, and as illustrated in the accompanying drawings,in which a preferred embodiment is disclosed in the drawings Figure 1 isa detail perspective of a car, some parts being broken away;

Fig. 2 is a sectional view on the line 2-2 of Fig. 1;

Fig. 3 is a sectional view on the line 3-3 of Flg. 1;

Fig' l is a sectional view on the line ls-d of Fig. 1; and

Fig; 5 is a detail plan view of the car.

The side walls of the car are shown at 19, 11; its side plates at 12,13, and its fascia platesat 14L, 15. At 16 is shown one of its carlines,and at 17, 17, the usual purlins. A. roof lining 18 of wood may or maynot be interposed hetween the framing of the roof and the metal plates19.

The plates 19 extend entirely across the roof, and at their ends areflanged downwardly, as shown at 29, to overlap the fascia plates 14%,15, the latter being prefer ably rabbeted to loosely receive the flange,as most plainly shown in Fig. 3. The side edges of each of the plates 19are turned upwardly, and preferably backwardly, as shown at 21 (Fig. 4).The several roofing plates 19 are spaced apart, and over the adyacentedges of each pair is placed a sheet metal binding strip 22,transversely bowed to looselycover the upturned edges 21 of the sheets,its side margins being laterally extended. from the bowed portion toform feet 23, 2t, which rest firmly upon the body portion of the tworoofing sheets with which UConnon,

atits outerend in a bracket 27, secured to the fasciaplate 14s, as bymeans of a bolt 28'- passing through these elements and I through theplate 12. Two of thefrods 26 are used in connection with each of thestrips 22, one at each side of the roof, the

inner or upper end of each rod being an chored' in abraeket 29, securedto a saddle block 30 mounted upon the ridge of the roof and carrying therunning boards 31. At least one end of each of the rods 26 is threaded,in the construction shown threads being formed at the inner end, toreceive a nut 32 by means of which the rods may be placed under tensionin order to bind the strips 22 upon the plates 19 and hold the saddleblocks and running boards in position.

By the means described the roof plates are secured without the use ofnails or screws, or other means requiring their perforation. Theirupturned. marginal edges, in cooperation with the binding strips,exclude the weather, dust and moisture. The binding strips 22 are ofmetal, such as steel, having a sufficient degree of elasticity to causea spring pressure upon the plates 19. The latter plates, however, havesufficient freedom of movement under the feet of the binding strips, andalso by reason oftheir loose engagement with the fascia plates, torelieve them of all strains incident to the twisting or weaving actionof the car.

ll claim as my invention- 1. A car roof comprising, in combination,sheet metal plates extending from side to side of the car and havingtheir side margins upturned, adiacent plates being spaced apart,transverse y bowed binding strips seated on adjacent plates and looselycovering the margins thereof, saddle blocks seated on the strips at theridge of the roof, and binding rods anchored in the saddle blocks and inthe framing of the car and located on the median lineof the bindingstrips.

2. A car roof comprising, in combination,

sheet metal plates adapted to rest loosely Iii plates being spacedapart, transversely bowed binding strips loosely coveringthe margins ofadjacent plates and adapted to yieldingly bear upon the body portions ofsuch plates, and means extending throughout substantially their entirelength for compressing the strips upon the plates.

3. .A carroof comprising, in combination, sheet metal plates extendingfrom side to side of the car and having their side margins upturned,adjacent plates being spaced apart, transversely bowed binding stripsloosely covering the margins of adjacent plates and each having achannel on its median line, a saddle block seated upon each strip at theridge of the roof,- and binding rods anchored in the saddle block and inthe framing of the car and fitting within the channels of the strips.

.4. A car roof comprising, in combination, sheet metal plates extendingfrom side to side of the car and having their side margins upturned,adjacent plates being spaced. apart, transversely bowed binding stripsloosely covering the margins of adjacent plates and each having alongitudinal depression forming a groove on its upper surface adjacentits median line, a saddle block seated upon each strip at the ridge ofthe roof, binding rods anchored in the saddle block and in the sideframing of the car and fitting within the depression of the.

narasee portions of such lates, and means wholly external thereof orcompressing the strips upon the plates. 1

6. A car roof comprising, in combination, a longitudinal series ofunconnected sheet metal plates resting loosely upon and covering theroof framing of" the car, each plate extending continuously from side toside of the car and each alternate plate overlapping both of theadjacent plates, and a bindin strip extending over each of the saidalternate plates and having its ends anchored to the car sides.

7. A car roof comprising, in combination, a longitudinal series ofunconnected sheet metal plates resting upon and covering the roofframing of the car, each plate extending continuously from side to sldeof the car and each alternate plate having upturned side margins, eachof the remaining plates being transversely bowed to loosely cover theupturned side margins of adjacent plates and yieldingly bear upon thebody portions of such plates at a substantial distance from the saidupturned margins, and binding strips extending over the bowed plates andhaving their ends anchored to the car sides,

8., A car roof comprising, in combination, sheet metal plates adapted torest loosely upon the roof framing of the car and having their sidemargins upturned, adjacent plates being spaced apart, the ends of theplates being flanged downwardly to loosely overlap the fascia plates ofthe car, tram versely bowed bindmg strips loosely covering the marginsof adjacent plates each strip having a central portion adapted to reston the roof framin between the edges of ad" jacent plates an 1 sideportions adapted to yieldingly bear upon the body portions of suchplates, and means wholly external thereof for compressing the stripsupon the plates.
